I am new to aquariums and owning fish. I have a 23 UK gallon aquarium with 3 Tin foil barbs, 6 (now 2) Clown loach and 2 Catfish.
4 Days ago all 6 of my Clown loach developed Ich

. I done some research on treating Ich and decided to do regular 50% water changes with added small amounts of aquarium salt (1 tablespoon/5 gallons) and also turn the temperature up to 80F. Last night 4 of my Clown loach died, the outbreak of Ich does not seem to be slowing. My Tin foil barbs and Catfish do not have any white spots like the Clown loach do, however this morning I noticed my Barbs flashing against the decor.
Can anybody give me any help or advise on saving my two remaining Clown loach and to prevent my Barbs and Catfish from developing Ich.
Many thanks.
PS. I have read that Clown loach are not for beginners in the hobby, I can totally see why now, very sensitive fish.
